Question

我目前已经设置了Spring Boot Zuul服务器，Spring Boot Eureka服务器和Python Flask微服务。

python微服务注册没有问题，并且向Heart Boot Eureka Server发送心跳，甚至出现在http://localhost:8761/的“当前已向Eureka注册的实例”下

当我启动Zuul服务器（打开紧急加载）并得到此消息时，就会发生此问题

DynamicServerListLoadBalancer for client myservice initialized: DynamicServerListLoadBalancer:{NFLoadBalancer:name=myservice,current list of Servers=[],Load balancer stats=Zone stats: {},Server stats: []}ServerList:org.springframework.cloud.netflix.ribbon.eureka.DomainExtractingServerList@446a5aa5

Zuul服务器能够找到自己的位置

DynamicServerListLoadBalancer for client 3102-ZUUL-SERVER initialized: DynamicServerListLoadBalancer: NFLoadBalancer:name=3102-ZUUL-SERVER,current list of Servers=[192.168.99.1:8762],Load balancer stats=Zone stats: {defaultzone=[Zone:defaultzone;  Instance count:1;   Active connections count: 0;    Circuit breaker tripped count: 0;   Active connections per server: 0.0;]

我尝试使用Postman向http://localhost:8761/eureka/apps/发送请求，并能够检索到如下所示的信息

<application>
    <name>myservice</name>
    <instance>
        <instanceId>YOLO8889:8889</instanceId>
        <hostName>localhost</hostName>
        <app>myservice</app>
        <ipAddr>localhost</ipAddr>
        <status>UP</status>
        <overriddenstatus>UNKNOWN</overriddenstatus>
        <port enabled="true">8889</port>
        <securePort enabled="false">7002</securePort>
        <countryId>1</countryId>
        <dataCenterInfo class="com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo">
            <name>MyOwn</name>
        </dataCenterInfo>
        <leaseInfo>
            <renewalIntervalInSecs>30</renewalIntervalInSecs>
            <durationInSecs>90</durationInSecs>
            <registrationTimestamp>1573932309374</registrationTimestamp>
            <lastRenewalTimestamp>1573932959485</lastRenewalTimestamp>
            <evictionTimestamp>0</evictionTimestamp>
            <serviceUpTimestamp>1573932308869</serviceUpTimestamp>
        </leaseInfo>
        <metadata class="java.util.Collections$EmptyMap"/>
        <isCoordinatingDiscoveryServer>false</isCoordinatingDiscoveryServer>
        <lastUpdatedTimestamp>1573932309374</lastUpdatedTimestamp>
        <lastDirtyTimestamp>1573932308869</lastDirtyTimestamp>
        <actionType>ADDED</actionType>
    </instance>
</application>

由于list of Servers为空，每次我尝试通过Zuul访问服务时，Zuul服务器都会引发异常Load balancer does not have available server for client。

如何让Zuul为我的python服务选择IP地址？

谢谢！
